Hi Bob.
I saw this request before. The reason I, and I'm sure many others, avoided
trying to answer your questions, is that we have far to little information to
provide a valuable answer! We have no information on the tower design
specification, nor any clear knowledge of the antenna loads to be expected
from the antenna.
Please contact the tower and antenna manufacturers to get the information
required to answer your questions. Enlisting the service of a local P.E. will
also be required to ensure that your installation conforms to the municipal
code cited by your local planning authority.
